As of September 25, 2020, the race will be allowed to continue at the Jackson Park Grove A & B locations with a maximum of 50 participants for the 50K race and 50 participants for the 50 mile race. The races will have separate start/finish areas and times to comply with the Chicago Park District permitting requirements. Final details are still pending for the race course, which will be on the lakefront path on the east side of Lake Shore Drive. All of the race information below is subject to change.

Southside Location. The Start/Finish Area is located at Jackson Park Grove 19A & 19B. The address is 5700 E. Hayes Drive, Chicago, IL 60649. This is also 6300 S. Lake Shore Drive, Chicago, IL 60649, on the West side of Lake Shore Dr.
50M: 6:30 AM (11-hour time limit) - Note that start time might move to 7:30 AM
50K: 8:30 AM (9-hour time limit)
Early Start Option:
Early starts are available to any runner who wants to do so but you will not officially be in the competition (overall or age group).
The way it works is to first see Pat Onines (Co-Race Director) on race day at the Start/Finish area. He will add you to the early start list. He will also mark the bottom of your bib # with an “ES”. You may then start whenever you wish and time yourself. You’ll be responsible to know the course especially where the turn-around is, and aid stations might not be available until the official race starts. When you finish, you’ll get a medal and a “Finished” in the official results with no time. Be sure to let the finish line crew know you were an early starter to avoid any confusion with those being timed. They will take the bottom of your bib # and give it to Pat as evidence of your finish.
Please remember that early starters or those that finish after the race time limit will have a “Finished” in the results but will not receive a position or a time.
